10 CFR PART 50, APPENDIX R ISSUE

"During part of the Appendix R safe shutdown circuit review, it was discovered that a fire in the screenhouse could cause grounds to undervoltage cable L785 for bus 17 that could blow the control circuit fuses for 'B' D/G, preventing it from starting. The 'A' D/G would not be available for a fire in the screenhouse since it does not have an isolation breaker located outside the screenhouse to isolate the 'A' D/G from bus 18. Consequently, neither D/G would operate without repairs to place the 'B' D/G to local and replace the blown fuses."

OFFSITE NOTIFICATION DUE TO A SULFURIC ACID LEAK CONTAINED ON SITE

"This 4-hour telephone notification is being provided in accordance with 10CFR50.72(b)(2)(vi) for notification of other government agencies. For the event below, on September 19, 2000, at 0920 PDT, SCE notified the Department of Environmental Health and the Office of Emergency Services (OES Incident number 00-4232). This notification was delayed due to an internal miscommunication.

"On September 19, 2000, at about 0730 PDT, control room personnel were notified of a sulfuric acid leak from the High Flow Makeup Demineralizer Bulk Acid Storage Tank. The leak was from a gasket located between level transmitter 2/3LT5045 and isolation valve AST-38. The isolation valve was closed and the leak stopped. All acid (estimated to be about 650 gallons) was contained within the tank's bermed area and then routed to the waste neutralization sump. The entire sump contents (about 2,500 gallons of sulfuric acid and water) were removed for disposal off-site. This occurrence was not a significant impact to the environment and did not hamper site personnel in the performance of their duties necessary for safe operation.

"At the time of this occurrence, both Units 2 and 3 were operating at about 100 percent power; Unit 1 remains permanently defueled. SCE will notify the NRC resident inspectors about this notification and will provide them with a copy of this report."

LICENSEE 24-HOUR REPORT

"While 12 Pretreated Water Storage Tank (PTWST) was removed from service for planned maintenance, the Diesel Driven Fire Pump was also removed from service to realign its suction flowpath to 11 PTWST on 7/6/00. Per the Technical Requirements Manual, this nonconformance requires that a Special Report be submitted to the NRC, by telephone, within 24 hours."
